THE SCIENCE BEHIND IT:Sorry this didn't make it to the video, and I see a few of you are asking. I didn't think about it until you guys all made very valid points.

1. The holes are for ventilation. Some smaller dirt pieces could fall out potentially but the holes are super small & the mulch is usually kind of stuck together, so I think it will work out.

2. As for timeline, It depends on the temperature -- heat speeds it up, as does what you put in. It can go from 16 days to a year depending. I'll keep you posted on mine.

3. The rolling is to help break it up and mix the dryer ingredients (leaves etc) in with the wetter ingredients (food scraps etc) to create a balanced biodegrade. You want equal (as best you can) amount of both.
